FLUSBING VALVE.

Application med September 28, 1921. Serial lb. 508,882.

To all whom it ma concern.'

Be it known t at I, KARL RnzNIcnx, a citizen of the United States and resident of New York in the county o New York and State of ew York, have invented certain new and useful Improvements in Flushin Valves, of which the following is a speci cation.

This invention relates to flushing valves, its objects are to make a flushing valve of low manufacturing cost and of high eiliciency for water closet bowls and other purposes.

In the accompanying drawings, forming a part hereof,

Fig. 1 is a vertical central section of a ushmg valve embodying this invention, and

Fig. 2 a side elevation thereof, portions being broken away for greater clearness.

In the drawings, the upstanding casing 1 has at the lower end of its side wall an 1ntake port 2 for connection of a feed water pipe, from which water under head iiows into and through the casing.

e casing bottom has an outlet port 3 for connection with a discharge pipe.

Within the casing chamber 1s an upstanding, integral, tubular, water escape conduit 4 having an exterior diameter less than the interior diameter of the casing chamber. The chamber between the casing wall and this water escape conduit is indlcated by 5 and extends upwardly above the upper end of the escape conduit part way to the top of the casing. The chamber of conduit 4 is indicated by 6. Within the upper portion of chamber 5 there is mounted a removable, upstanding water receiving cup 7 having in its side a water intake port 7* of small diameter, whereby the upper portion of chamber 5 and the chamber 6 of the cup are in constant communication. This cup 7 constitutes the main valve. The bottom of the cupped main valve is centrally provided with a water escape port enclosed by a valve seat 8. An exteriorly threaded tubular extension 9 from the valve seat and bottom of the cup extends downwardly into the upper end of chamber 6. A poppet valve having a disc shaped body member 10 which has its under Th eripheral margin reduced at 11 to a lesser diameter than that of its top portion, s mounted on the upper surface o a asket 12 of lesser diameter than that of t e reduced valve body portion 11. The gasket to permit the on the valve seat for e when the valve body the valved cup 7.

The valve body gasket and valve stem are tlltable by lateral pressure on the de endent under end of the valve stem withm the chamber 6, for unseating the valve. For this purpose the lower end of the casin is formed with a horizontal, tubular extenslon 1 through which a valve stem tilting rod having an outer end lianged head 14 projectlng into the chamber 6 and into working contact with the valve stem shank. The outer end of the valve stem tilting rod 14, out wardly of the casing extension 1, is operated by a handle grip 15 which projects horizon tally from the casing and is workable against the tension of a horizontal coiled spring 16 inwardly of the iian ed head 14* of the tilting rod 14 and enc osing the latter within the chamber of a hollow nut 17.

he open top of the casing is covered by a removal cap 18 havin an exterior to nut 18 for application o a Wrench.' This cover cap is threaded to the casin at 19 and carries on its under side a centraly disposed, downwardly projecting stop pin 20, the upper end of which is secured to the cap at e cupped main valve 7 has its bottom resting on an annular gasket 21 which surrounds the de endent extension 9 of the cup and bears on t e upper horizontal end of the water escape condult 4. An annular gasket 22 is interposed between the cap 18 and the upper end wall of the casi adjacent the threaded union of the cap an casing at 19. The under end of the sto in 20 is sli htly above the upper surface o t e valve b 10. e upper end of the cupped main va ve 7 has an annular flanged nut 23 Screwed to it at 23l the chamber 6 of the cupped main valve being in constant communication with the chamber 2i of the cap through the annular gasket 22. The flange of t e nut 23 is indicated by 23` and it clamps the inturned flange 33* of a tubular gasket 33 against the upper end of the upstanding, open topped, cupped main valve. The lower ortion of the gasket 33 encloses the brim of t e cupped main valve and the exterior wall of the gasket 33 together with the periphery of the flange 23" are in sliding relation to the 1nterior wall of the casing 1. The lower end portion of the side wall of the cup 7 is conveniently provided with perlpherally projecting abutments the outer surfaces of which are arced but are out of contact with the inner wall of the casing 1 in order to form a series of restricted water passages between the under portion of chamber below the bottom portion of the cup 7 and the upper portion of the chamber 5 where it surrounds the bod of the cup 7 and finds entrance through t e port 7 into the chamber 6 of the cup. n

The inward end of the valve stem tiltlng rod 14 is, within the chamber 6, provided with an interiorly threaded nut 25, the open end of which projects outwardly and at 26 is threaded on the inwardly projecting tubular end of the spring containing nut 17 which is contained in t e bore of the tubular casing extension 1. The tilting rod 14 extends throu h the nut 17. The outward end of the nut 1 is exteriorly threaded for connection at y with a chambered, handlebar carrying nut 17* which, at y', has a threaded connection with the bore of the casing extension 1.

The inwardly facin bottom wall of the chamber of the nut 1 is concave and the half round head 27 of the handle bar 27 bears rockingly on such concave wall. The inward end of the head 27 is flat and bears against the flat outward end wall of the flan e head 14l of the tilting bar 14. The handle b ar 27 is rovided inwardly of its end with a shou der against which the flan ed end 28 of a sleeve on the handle bar is a-utted. The handle grip 15 has its inward end fitted to this flanged sleeve 28, the handle bar 27 extending through an axial opening of the handle gri 15, the butt end o which is held in place y a flanged butt end nut 29 threaded on the outer end of the handle bar 27.

Referring to the construction of the valve body as a whole, it is to be observed that the reduced portion 11 of the valve body l0 has its under mar in annularly overhanging the gasket 12; an that by the reduction in diameter of the under end of the valve body 10 its under margin overhangs annularly the reduced portion 11. By this construction the tiltable valve body is given a step-up peri heral contour.

e operation of this flushing valve is as follows:

When it is installed and before water is Leemans let on the tiltable valve seats itself by gravity. When the water under head has entered the intake ort 2 it flows into the chamber 5 around t e escape conduit 4 and rises thence slowly through the restricted passa es m into the upper portion of the cham er 5 between the casing wall and the body of the cupped main valve; and thence flows slowly through the small port 7, gradually lilling the chamber 6 and rising u wardly into the communicating cap c amber 24, whereby, in the chambers 24 and 6, which practically constitute one chamber, a'pressure is built up and exerts itself against the valve body 10 to hold the same iirmly seated, the gasket 12 then being compressively forced against the valve seat anvpreventing leaka e.

enever the han le trip is pulled down, or, in fact, moved in any direction, it is so moved against a tension of the coiled spring 16 and cants the shank of the valve stem within the water escape chamber 6, thus sli htly lifting an edge portion of the gasket o the valve seat. The water under ressure in the chamber 6 then tends to {lldw out. IThe cupped main valve is vertically reciprocable in reference to the upper end of the conduit 4; and the small port 7 of restricted area is in a side wall of the cupped main valve above the restricted passage between the lower portion of the cupped valve and the thereto opposed interior wall of the main casing.

What I claim is:

A flushing valve comprising in combination, a vertically chambered main casing having in its lower portion an upstanding tubular water esca e conduit the peripher of which is space apart from the oppose interior Wall of the casing; the casing wall and the wall of the escape conduit being integral with a tubular extension open at its outer end and opening into the water escape port; a vertically movable, cup ed main valve, seatable on the upper end o the tubular escape conduit above the said extension; the upper end of the cup ed main valve being 4provided with a ho low nut and a gasket the peripheries of which are in sliding relation to the interior wall of the u per portion of the casingl; the side wall o the cupped main valve aving a water intake port of restricted dimensions below said gasket and nut, and above its under end portion; the under end wall of the cupped main valve having a water escape port communicating with said water escape conduit; and the peripheral wall of the under end portion of t e cup d main valve being dimensioned relative y to the thereto opposed portion of the main casin to form a restricted waterway between a chamber, the lower portion of which is around the water escape conduit and the upper portion of which is around the main valve below said gasket; a poppet valve mounted in the water escape port of the main valve and having a stem projectin downwardly into the waterescape condult; a stop to limit the upward movement of the poppet valve; and a movable actuating handle having a member in continuous engagement with the stem of the puppet valve and a detachable cover for the u per end of the main casing.
